[arch-projects] [RFC] [PATCH] [mkinitcpio] Cleanly stop udev >= 168 as recommended by upstream.

N0: udev >= 168 is needed. N1: I guess the order is correct (first cleanup then exit). N2: device-mapper/LVM udev rules must be parsed for initramfs creation to add OPTIONS+="db_persist" >From udev NEWS: The running udev daemon can now cleanly shut down with: udevadm control --exit Udev in initramfs should clean the state of the udev database with: udevadm info --cleanup-db which will remove all state left behind from events/rules in initramfs. If initramfs uses --cleanup-db and device-mapper/LVM, the rules in initramfs need to add OPTIONS+="db_persist" for all dm devices. This will prevent removal of the udev database for these devices.
